集群管理

# 启动zookeeper
bin/zookeeper-server-start.sh config/zookeeper.properties &# 停止zookeeper
bin/zookeeper-server-stop.sh# 前台启动broker Ctrl + C 关闭
bin/kafka-server-start.sh <path>/server.properties# 后台启动broker
bin/kafka-server-start.sh -daemon <path>/server.properties# 关闭broker
bin/kafka-server-stop.sh

topic相关

# 创建topic（4个分区，2个副本）
bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 2 --partitions 4 --topic test
# kafka版本 >= 2.2
bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic test--create：指定创建topic动作--topic：指定新建topic的名称--zookeeper： 指定kafka连接zk的连接url，该值和server.properties文件中的配置项{zookeeper.connect}一样--partitions：指定当前创建的kafka分区数量，默认为1个--replication-factor：指定每个分区的复制因子个数，默认1个# 分区扩容，注意：分区数量只能增加，不能减少
# kafka版本 < 2.2
bin/kafka-topics.sh --zookeeper localhost:2181 --alter --topic topic1 --partitions 2
# kafka版本 >= 2.2
bin/kafka-topics.sh --bootstrap-server broker_host:port --alter --topic topic1 --partitions 2# 删除topic
bin/kafka-topics.sh --zookeeper localhost:2181 --delete --topic test# 查询topic列表
bin/kafka-topics.sh --zookeeper 127.0.0.1:2181 --list
# 查询topic列表（支持0.9版本+）
bin/kafka-topics.sh --list --bootstrap-server localhost:9092# 查看所有topic的详细信息
bin/kafka-topics.sh --zookeeper 127.0.0.1:2181 --describe # 查询topic详情
bin/kafka-topics.sh --zookeeper localhost:2181 --describe --topic topicname

消费者组

查看consumer group列表有新、旧两种命令，分别查看新版(信息保存在broker中)consumer列表和老版(信息保存在zookeeper中)consumer列表，因而需要区分指定bootstrap–server和zookeeper参数

# 新消费者列表查询（支持0.9版本+）
bin/kafka-consumer-groups.sh --new-consumer --bootstrap-server localhost:9092 --list
# 消费者列表查询（支持0.10版本+）
bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --list# 显示某个消费组的消费详情（仅支持offset存储在zookeeper上的）
bin/kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --zookeeper localhost:2181 --group test
# 显示某个新消费组的消费详情（0.9版本 - 0.10.1.0 之前）
bin/kafka-consumer-groups.sh --new-consumer --bootstrap-server localhost:9092 --describe --group my-group
## 显示某个消费组的消费详情（0.10.1.0版本+）
bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --describe --group my-group# 重设消费者组位移
# 最早处
bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --group groupname --reset-offsets --all-topics --to-earliest --execute
# 最新处
bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --group groupname --reset-offsets --all-topics --to-latest --execute
# 某个位置
bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --group groupname --reset-offsets --all-topics --to-offset 2000 --execute
# 调整到某个时间之后的最早位移
bin/kafka-consumer-groups.sh --bootstrap-server localhost:9092 --group groupname --reset-offsets --all-topics --to-datetime 2019-09-15T00:00:00.000# 删除消费者组
bin/kafka-consumer-groups.sh --zookeeper localhost:2181 --delete --group groupname

显示某个消费组的消费详情

各字段含义如下

TOPIC	PARTITION	CURRENT-OFFSET	LOG-END-OFFSET	LAG	CONSUMER-ID	HOST	CLIENT-ID
topic名字	分区id	当前已消费的条数	总条数	未消费的条数	消费id	主机ip	客户端id

发送和消费

# 生产者
bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test# 消费者,其中"--from-beginning"为可选参数，表示要从头消费消息
bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic topicname --from-beginning
# 指定groupid
bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic topicname --from-beginning --consumer-property group.id=old-consumer-group
# 指定分区
bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic topicname --from-beginning --partition 0# 新生产者（支持0.9版本+）
bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test --producer.config config/producer.properties# 新消费者（支持0.9版本+）
bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --new-consumer --from-beginning --consumer.config config/consumer.properties# kafka-verifiable-consumer.sh（消费者事件，例如：offset提交等）
bin/kafka-verifiable-consumer.sh --broker-list localhost:9092 --topic test --group-id groupName# 高级点的用法
bin/kafka-simple-consumer-shell.sh --brist localhost:9092 --topic test --partition 0 --offset 1234  --max-messages 10

切换leader

# kafka版本 <= 2.4
bin/kafka-preferred-replica-election.sh --zookeeper zk_host:port/chroot# kafka新版本
bin/kafka-preferred-replica-election.sh --bootstrap-server broker_host:port

kafka自带压测命令

bin/kafka-producer-perf-test.sh --topic test --num-records 100 --record-size 1 --throughput 100  --producer-props bootstrap.servers=localhost:9092

kafka持续发送消息

持续发送消息到指定的topic中，且每条发送的消息都会有响应信息：

kafka-verifiable-producer.sh --broker-list $(hostname -i):9092 --topic test --max-messages 100000

zookeeper-shell.sh

如果kafka集群的zk配置了chroot路径，那么需要加上/path。

bin/zookeeper-shell.sh localhost:2181[/path]
ls /brokers/ids
get /brokers/ids/0
